Naturally-occurring and human-engineered alterations in our shoreline area can result in modifications to shoreline jurisdiction boundaries when an action changes the "ordinary high water mark" or other physical characteristics that determine jurisdiction of the state Shoreline Management Act. Examples of such alterations include:
- Permitted, human-engineered changes such as filling and dredging
- Flood-control projects
- Natural changes due to landslides, flooding, channel alterations, and river course changes
Shoreline master programs officially delineate shoreline jurisdiction
When Ecology approves a locally-tailored, updated comprehensive shoreline master program from a city or county, our decision means the water bodies covered under state law have been delineated. Each shoreline program contains maps and legal descriptions of these delineated streams and rivers, lakes, shorelines and wetlands.
